NUT-LeereA SPECIFICATION forming part of Letters Patent No. 723,030, dated March 17, 1903. Appiimion filed August 2s, 1902. serai No. 1212318. (No modem,

To all whom/'it may concern.:

. Beitknownthat LWILLIAM U.RosENrHAL, a citizen of the'United'States, residing at New Orleans, in; theparishof Orleans and State of Louisiana, have invented-new and useful Improvements in Nut-Locks, of. which `the following is aspecification.

This invention relates to certain new and useful improvements in nut-locks, and it is particularly adapted for use for connecting the meeting. ends ofrailroad-rails together and for other purposes for which it can be used.

The invention aims to provide a nut-lock `which shallbe extremely simple in its construction, strong, durable, efficient in its use, and comparatively inexpensive to set up and to this end it consistsof the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part-of this specification, wherein like reference characters denote corresponding parts throughout the several views, and inwhich l Figure lis a frontelevation of the nut-lock, showing the' saine connecting a pairof railsections together.- Fig. 2 is a sectional view thereof, and Fig. 3 is a sectional elevation of a modified form.

` Referring to the drawings by reference characters,which for illustration l have shown my improved nut-lock in position for connecting a pair of rail-sections together, l and 2 denote the rail-sections, and 3 denotes one of the fish-plates usually employed for connecting rail -sections-,f` together and is provided with openings through whichextend the headed bolts 4. The {ish-plate 3 is ofl the ordinary construction, arranged at one side of the rail- I sections so itwill engage the lower face of the tread ofthe rail, the web of the rail and the base of the railpreferably extending over the top of the base of the rail and flanged at its lower end, so as to engage the edge of the base.

The reference character 5 denotes the fishplate, which is arranged against the rail-sections opposite tothat of the fish-plate 3, and is also provided with a series of openings,

through which is adapted to extend the end offthe bolts 4. The inner face of the fishplate 5 is preferably of the same construction as that of the fish-plate 3-that is, engages the web and base of the rail in the same manner as the fish-plate 3. The fish-plate 5 at its top is provided with an outward-extendinglange 6, which is of the same length as the fish-plate, or, in other words, projects laterallyfrom .the top of the fish-plate 5 throughout its entire length and is provided with a plurality of openings 7. The iiange 8 at the lower portion of the fish-plate 5 is provided with a plurality of recesses 9, forming seats. Instead of the recesses being provided in the flange 8` a plurality of openings may be employed instead. l The reference character l0 denotes a plurality of locking-pins, which extend through the opening 7 and engage inthe seats 9. The locking-pins l0 may be constructed of any suitable metal, but preferably malleable iron, so that when they are driven home the lower ends of the pins will swag and form a tight fit in the .recesses 9. This will prevent the withdrawal of the `locking-pins l0 when in their locking position.` The openings 7 in the fiange 6 are of-such` a diameter that the pins will tightly fit therein. The pins are adapted to be driven in their locking position-that is to say, the diameter of the openings 7 and the recesses 9 are such that after the pins are driven home they will tightly t therein. Mounted upon the extended ends of the bolts 4 are the washers ll and the nuts 121.

1 The nut-lock-is set up as follows: The two rail-'sections areplaced in position, the iishplate 3 placed against one side of the rail-sections, the fish-plate 5 placed against the opposite side of the rail-sections, thebolts 4 are extended through the fish-plates and the web of the rail, the washers l1 are placed upon theprojecting ends of the bolts, the nuts 12 are screwed home upon the bolts,and the locking-pins driven home, so that they will engage one side ef the nuts and prevent the turning thereof.; The flanges 6 7 of the lishplate 5 are arranged such a distance from the openings in the iish-plates through Which extend the bolts so as not to interfere with the screwing home of the nuts l2.

From the foregoing construction it will be evident that when the locking-pins are driven home and engage the sides of:` the nuts itwill be well nigh impossible for the nuts to turn, the locking-pins being in such position that they always engage one side of thc nuts and prevent their turning.

In the modified form of construction shown in Fig. 3 the fish-plates 13 14 are of the ordinary construction and are arranged against the side of the rail-sections, and a lockingplate is employed which is substantially the length of the fish-plates and is adapted to be arranged against the outer face of one of the `fish-plates--for example, the fish-plate 14, as shown in Fig. 3. The reference character 15 denotes the locking-plate, which is provided at its top and bottom, respectively, with the laterally-extending fianges 16 17, the former provided with a plurality of openings 18 and the latter with a plurality of recesses 19. Instead of providing the flange 17 with the recesses 19 the flange 17 may be provided with openings in the same manner as the flange 16. the locking-pin 2O is adapted to be arranged. The locking-pin 2O is of the same construction as the locking-pin 10. The operation of place ing the nut-lock in position in its modified form is the sameasthat hereinbefore referred toin connection with Figs. 1 and 2. In some instances it may not be necessary to employ the fish-plate 14.. Thereforeit can be dispensed with and the locking-plate 15 brought against lthe side of the rail adjacent to that which is engaged bythe fish-plate 13. It will be evident that the locking-plate l5 is provided with a plurality of' openings, through which extend the bolts.

In connection with the construction set forth in Figs.1 and 2 I term the fish-plate provided with the flanges the locki ng-plate land consider the same the equivalent of the lockingplate as shown in Fig. 3. Consequently the locking-plate in Fig. 3 may have its lower fiange extended in such a manner as to embrace the base of the rail.

Itis thoughtY thc many advantages of my improved nut-lock, especially of constructing the locking-pin of malleable iron, so when it is driven in the opening or recess of the lower flange in the locking-plate the lockingpin will spread, causing the pinto be securely held within the said recess or opening, and the arrangement of the pin with the nuts will prevent the nuts from turning, conse-` quently preventing a disengagement of the nut-lock in its entirety when set up to secure rail-sections, objects, or other parts of machinery where the nut-lock is applicable, and it will also be evident that I have devised a simple, inexpensive, and novel form of nutlock which can be readilyset up and employed for connecting railroad-rails together, parts of vehicles, machines, and apparatus of every description, and it will furthermore be evidentthat changes, variations, and modifications may be resorted to without departing Within the openings 18 and recesses 19,

from the spirit of the invention or sacrificing any of its advantages; and I therefore do not wish to restrict myself to the details of construction hereinbefore described and as shown in the accompanying drawings, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a nut-lock,the combination with a bolt and a nut, of a locking-plate mounted upon the bolt and provided with a pair of fianges out of contact with the nut, and a lockingpin having its ends extending into and secured in and to said fianges and further having a portion ot its length engaging one side of said nut to prevent its turning.

2. In combination with a bolt and a nut mounted thereon, of a plate mounted upon said bolt and provided with an upper and a lower flange extending laterally therefrom and out of contact with the nut, and a vertically-arranged pin having its ends extending into and secured in and to the said fianges and having a portion of its length engaging one side of said nut to prevent the turning thereof.

3. In combination with a bolt and a nut mounted thereon, of' a plate mounted upon the said bolt and provided with an upper and a lower flange extending laterally therefrom and out of contact with the nut, and a pin constructed of malleable iron and having its ends extending into and secured in and to said fianges and further having a portion of its length engaging in one side of the said nut to prevent the turning thereof.
